Why suddenly changing the norm ... ?
Why simply not publishing the extensive FDR time reference ... seconds included ?
"TGEN is the timing in seconds from the start of the DFDR reading made by the investigators."
Is it really too much asking than expecting the investigators to specify which GMT H:M:S has been selected ?
Yes, and I'm still inclined to the theory that TGEN 000.0 seconds is most likely to be the instant that TOGA was selected on T/O.
It would be surprising that TOGA or FLEX has been selected before any takeoff clearance, but again, FDR data would tell more ... if only published.
